MACHINE FOR MAKING CUT GLASS.

SPECIFICATION forming part of Letters Patent No. 765,304, dated. July19, 1904.

Application filed July 25, 1903. Serial No. 166,995. (No model.)

of Connecticut, have invented certain new and useful Improvements inMachines for Making Cut Glass, of which the following is aSpecification.

This invention relates to the art of manufacturing cut glassware; and ithas for one of its ob ects the provision of a machine whereby glassblanks of difi'erent shapes and sizes may be cut in accordance withvarious predetermined designs and ornaments and without the employmentof skilled labor.

A further object of the invention is the provision of a machine in whichthe blank to be cut may be presented to the cutting-wheel in differentpositions, so that cuts having an angular or other desired relation tothe axis of said blank may be produced.

A further object of the invention is the pro-- vision in connection witha blank support or holder of interchangeable devices for indexing saidholder to cause the blank to be presented to the cutting-wheel inaccordance with a predetermined design, thus enabling grooves to be cutat the required points withoutliability of mistake. 1

- A further object of the invention is the provision of means'for movingthe blank-support bodily past the cutting-wheel and for holding thesamein predetermined positions relatively to the cutting edge of said wheel,these means comprising interchangeable indexing devices for controllingthe positions of the blank to cause the cuts to be made inaccordance'with the design to be reproduced.

A further object of the invention is the provision of interchangeablepatterns or formers for controlling the movement of the blanksupporttoward the cutting instrument.

A further object of the invention is the provision of improved indexingand former or pattern controlling devices.

Further objects of the invention will be hereinafter set forth.

One of the principal aimsof the invention is the provision ofia machinein which the blank to be cut may be properly presented to the action ofthe cutting, polishing, or other wheel and in which the liability ofmistakes or irregularities in spacing the cuts according to the patternor design shall be minimized, a feature which is of great importancewhen it is considered that the value and beauty of the article dependsalmost entirely upon the manployed.

Fig. 10 is a sectionalview representing in detail the table and transversely-movable slide forthe blank and pattern. Fig. 11 is a top view of the axial indexingdevice. Fig. 12 illustrates one kind of an ornamental glass dish whichmay be produced by the improved machine, and Fig.

. 13 illustrates an attachment hereinafter described.

In the drawings the improved machine is illustrated comprising a pair ofside frames 20 21, tied together by rods 22, and secured upon the frame21 is a head 23, having bearings 24, in which is journaled a spindle 25,shown rotated by a belt 1n engagement with a cone-pulley 26, saidspindle carrying at its outer end a cutting-wheel 27, secured thereto inany convenient manner.

Other means may be employed for actuating the cutting-wheel, if desired.Here'it may be stated that the character of wheel 27 employed isimmaterial, as a polishing or other wheel may be substituted for thecuttingwheel shown, if desired.

Suspended above the wheel in use, which may be a grinding, smoothing, orpolishing wheel, is the usual reservoir R, containing sand and water orwater alone when smooth' ing is to be done, the flow of which may beregulated by a valve V and conducted to the wheel 27 by a trough T.

Secured to and mounted for vertical adjust ment on the side frames 21and 22 is a support 30, provided with slots 31 for the passage ofclamping-bolts 32, carried by said frames.

Upon the support is a frame 33, pivoted at 34 and having curved slots 35to permit of accurate adjustment, clamp-bolts 36 passing through saidslots and serving to secure the frame in position.

Mounted for movement on the frame 33 transversely of the cutting-wheel27 is a slide 40, having a dovetail projection 41 in engagement with acorr'espondinglyshaped groove in the frame and adapted to be clamped inlace b ,ascrew 42 en a in agib 43, which 9 b b b may be held against alongitudinal sliding movement by a projection 44, as shown in- S'ecuredto slide 40 is a plate 46,

Fig. 10. having a series 'of apertures 45, and when the screw 42 isloosened the slide 40 may be moved longitudinally to bring any one ofsaid apertures opposite a stop-pin 47. (See Fig. 9.)

This pin has preferably anenlarged head 48-, 1

serving as an abutment for a "spring 49, the other end of which restsagainst the bottom of a recess 50, formed in a bracket 51', which ispivoted at 52 on the frame 33, a nut 53 in screw-threaded engagementwith a bolt 54 serving firmly to clamp the bracket 51 in position, andthe aperture 55, through which the bolt 54 passes, being larger indiameter than said bolt to permit the bracket to have a slight angularmovement around the pivot 52 for a purpose hereinafter set forth.Secured to the slide 40 by bolts 60 is a plate 61-, and said slide hastransverse slots 40 of length and width to permit the plate not only tobe upper ends of the arms 65 are links 67, the lower ends of which aresecured to a frame 70, pivoted at 71 on the links, as shown in Fig. 2,while bolts 72, passing through slots 73 of the links, serve to securethe parts firmly together and also enable said links to be adjusted inan arcuate path and then secured in place. 7

Referring to Fig. 5, it will be seen that the frame is provided with abearing 74 for the reception of an arbor 75, the upper end of whichcarries a head 76, having a tapered recess 77. Head 76 constitutes thesupport or carrier for the blank to be cut, and as the arbor of saidhead is mounted for intermittent rotation in the bearing-74 any desiredpart of the surface of the blank to be out may be presented to theaction of the wheel 27.

Although it is immaterial how the blank B may be held on the arbor, Ihave illustrated one form of holder for such purpose, said holdercomprising a block 80, which conforms to some extent to the interior ofthe blank and with which the latter may be unitedas, for instance, bysealing-wax or other cementitious substance, as indicated at 81. Saidblock 80 is preferably made of wood and is Secured to a metallic plate82-, which is provided with a tapered shank 83, adapted to fit into thesimilarly-formed recess 77 of the head 76, in which it is secured by akey 84 or otherwise. In order to prevent the blank from becomingdetached from the block 80, extraneous clamping means may be employed,said means comprising in the form thereof shown a lever 85, fulcrumed at86 in aswivelblock 87, which may be rotatably held in a to be removedand another to be substitutedtherefor when required.

Means are provided for holding the arbor, and therefore the blank B,against rotation during the cutting operation, these means comprising anindex-plate 90, (see Fig. 11,) which may be held on the head 76 by asetscrew 91 or otherwise, and the periphery of which is provided with aseries of notches 92, corresponding to the cuts to be produced on theblank. These notches 92 are adapted to be engaged by adetent 93, (seeFig. 2,) pivoted at 94 on the bearing 74 and actuated by a spring 95,while said detent may be disengaged from the notches 92 by pressing uponthe tailpiece 93, as will be readily understood.

As shown in Fig. 11, the notches 92 are spaced circumferentially toindex the arbor 75 properly to bringthe blank B into contact Iro withthe cutting-wheel, sothat the latter may cut on the radial lines a inFig. 12, which represents a glass dish properly out according to thedesign, the position of the wheel cutting edge being indicated by theline 20, which would intersect the axis of rotation of the blank. v

From the above description it will be seen that the frame 7 0 may havetwo movementsviz., a partial revolution around the pivots and a rockingmovement with the arms 65 1 be varied to compensate for the wear of thecutting-wheel, it being understood, of course, that as the wheel wearsoff the blank should necessarily be advanced farther inward.

Referring to Fig. 5, it will be seen that the frame 7 0 is also providedwitha bearing 100 for an arbor 101, the upper end of which is chambered,as at 102, to receive a spindle 103,

which maybe adjusted vertically therein. and

secured in position by aset-screw 104 and which supports the model orpattern 105, as

clearly shown in Figs. 1, 3, and 5,.and in order to insure equalrotative movements of both blank and pattern the lower ends of thearbors 75 and 101 carry similar gears 106 107, respectively, inengagement with an intermediategear 108, journaledon a stud 109, whichmay be secured in a web 110, connecting the bearings 74 and 100. t V

Cooperating with the pattern 105 is a gagewheel 110, whereby the depthof cut to be made in the blank may. be regulated, this wheel beingpreferably journaled in the forward end of a slide 111, guided in ways112 of a block 113, in which the slide may be adjusted by a screw 114.(See Fig. 7..) This block 113 may be secured to the top of a bracket115, attached to the upper end of the side frame. 20 and in such amanner that the center line of the gage-wheel and its slide 111 will bein alinement with and intersect the axis of the .pattern-arbor.101,while the edgeof the cutting-wheel 27 is in alinement with the axis ofthe blank-supporting arbor 75. From this it follows that thecutting-wheel will act on the blank inthesame place in which thegage-wheel engages the pattern circumferen: tiallyand, furthermore,that. the depth of cut in the blank at that place is controlled by theform of the patternin conjunction with the position .of the gage-wheel.

In the drawings "the blank is shown oblong in shape, having roundedsides and a flat bottom, so that when it is desired to produce cuts likethose indicated by a the cutting-wheel must be permitted to cut deepernear the middle portion longitudinally of the cut and the a withdrawalof the blank from the wheel must be gradual. Hence the pattern is formedso as to accomplish this result by having projecting portions or ledgeso6 adapted toact as stops and engage the gage-wheel 110 when the frame isswung around its supportingtrunnions 65' and pushed bodily forwardtoward the cutting-wheel, it being understood, of course, that thedepressed or other surface 0 of the pattern between the stops is shapedto conform to the required cut.

As it is difficult to produce a clean and smooth out in the glass at oneoperation and if such were attempted the drag on the cuttingwheel wouldbe excessive when the full depth of the cut is reached, it is preferableto go' over the same cut a number of. times and to permit the depth ofout to be increased with each succeeding operation by successivelymoving the gage-wheel 110 rearward, and thus allowing the blank to beprogresively forced inward toward the wheel until the de-. sired depthhas been attained. Furthermore, when finishing the sides of some cuts itis preferable to operate on one side of each cut at a a time, and thismay be readily accomplished by. adjusting the bracket 51 of theindexingdevice for the slide &0.

Referring to Fig. 8, it will be seen that said bracket 51 has been movedsubstantially to its extreme position toward the right, where it isclamped rigidlyin place by the nut 53, and in this instance the leftsides of the cuts (indicated by a) may be finished, Whenthis Iadjustment of said bracket is made, the slide 40 and index-plate 4:6,inan opening of which the pin 4:7'is placed, are also moved a slightdistance toward the right, thereby carrying the blank-supporting andpattern devices in the same direction, and thus so locating the blankthat the wheel willdress the left side ofthe cut. After the left side ofone out has been dressed the plate.90 will be indexed to turn theblank-holder intermittingly until the left side of another cut isbrought into posi tion for the dressing operation, and so on until theleft sides of all the cuts have been operated upon by the wheel 27,aft-er which the nut 53 will be turned to release the bracket 51, andthereby so'locate the parts .that the cutting-wheel will operate upontheright side of a cut and upon the same side of each succeeding cut of theseries, the plate 90 being of course :then again indexed properly tospace the cut.

' Referring, now to Fig. 13, the numcral'120 designatesa link havinga-slot 121,"said link being connected to hearing 74c atoneend and 6oried by the slide may be tilted on the pivoti the blank and forcedagainst the same by screw 89. An interchangeable pattern 105 of thedesired form to produce the required design is then mounted upon thearbor 103 in such a manner that similar portions of the pattern and theblank will be opposite the edges of the gage-wheel 110 and cutting-wheel27, respectively, and said wheel 27 being set in motion and a supply ofsand and water furnished thereto by opening the valve V the operatorgrasps the handle H with his right hand, pushing with his other handagainst the upper end of the left arm 65, and thus bringing the surfaceof the pattern, or more specifically the ledge or stop 6 thereof, intocontact with the gagewheel 110, the position of which is such as topermit the cutting-wheel 27 to clear the blank. By now swinging theframe 70 around its trunnions 65the blank will be rolled in front of thecutting-wheel in conformity to the shape of the surface 0 of the pattern105 in use, said wheel cutting into the glass and again clearing it whenthe ledge or stop Z) engages the gage-wheel 110. By now indexing theblank-arbor 75 until the detent 93 enters the next succeeding notch ofthe plate 90 (this action resulting by virtue of the gearing 106, 107,and 108 in a similar and simultaneous movement of the pattern 105) theblank is turned to bring a new space thereof opposite the wheel,whereupon the frame 70 is again manipulated, as before, and the wheel 27will consequently make asecond cut, governed by the surface 0 of thepattern into the blank, these operations being repeated until all theperipheral cuts (indicated by a in Fig. 12) have been made, said cutsbeing preferably of but partial depth. Slide 111 is now moved slightlyrearward, and the frame 70 is manipulated as before, and the sameprocedure is carried out repeatedly until the fulldepth of out has beenobtained. If desired, however, each cut may be made of full depth at asingle operation.

From what has been stated it will be seen that provision is made formany kinds of adjustment by which the-blank-support may be presented at.various angles to the tool employed. Thus byfirst moving the slide 40and then releasing the nuts 36 the parts carbolt 34 to present the blankB in an inclined position laterally to the cutting or polishingimplement employed, so that said implement will then produce or polishdiagonal cuts or lines on said blank. When the blank-support is tiltedat the desired angle to the right and the frame 33 is locked in suchposition by the nuts 36, lines or cuts inclined to the right may beformed, and when said frame is tilted toward the left, lines or cutsinclined toward the left will result when the blank is forced againstthe implement. By loosening the nuts the plate 61 may be adjusted in ahorizontal plane in an arcuate path to present the blank-holder at stilldifferent angles to the implement, and said plate may also be moved backand forth upon the slide 10 to locate the size of blank to be operatedupon properly with relation to the cutting, smoothing, or polishingtool, and by loosening the bolts 72, passing through the curved slots 73of links 67, the frame 70 may be adjustedon said links to vary the angleordip of the blank-support with relation to the tool. Frames 33 70 andall the parts carried by said frames may also be vertically adjusted onthe standards 20 21 by loosening the bolts 32, moving the slottedcross-strip 30 up or down, and then retightening said bolts.

In forming the drop cuts d on the bottom of the glass (shown in Fig. 12)the slide 40 is indexed longitudinally by plate 16 and stoppin 47, andthen by swinging the frame 70 by handle H to the proper position, asshown in Fig. 13, the bottom of the blank may be pre sented to theaction of tool 27, and after one out has been made the slide 40 is againindexed to determine the desired spacing of the cuts, and theseoperations are repeated until the desired number of cuts is obtained.When this operation is to be carried out, the attachment, consisting ofa curved link 120, having a slot 121, through which passes a bolt 122,secured by a nut 123, is utilized to lock the frame 70 in position,after which said cuts d may be formed by grasping handle H and forcingthe frame 70 and arms inward toward the wheel 27 until the top of theformer engages roll 110 or other stop. 1n virtue of this attachment theframe may be adjusted to present the blank B at the desired angle to thewheel 27 and then firmly secured in position.

by tightening nut 123, and after one cut d has been formed the othersmay be produced by indexing the slide 40 in the manner above described.Other means may be substituted for locking the frame in the positionsjust described without departure from the invention. Cuts on tangentiallines may also be readily produced by angularly adjusting the frame 33,carrying slide 40, so that the edge of the wheel 27 will be presented tothe blank in the desired position.

To form an ornament or star like that indicated by e in Fig. 12, theslide 10 is indexed to position the blank properly with relation to thecutting-wheel, and the arbor is then other without departure from theinvention.

indexed about thirty degrees after each out has been made.

From what has been stated it is evident that ornaments and designs ofany desired kind may be accurately produced and that with a former orpattern of one shape a set of articles each havingthe same precisionizedornamental surface may be readily made.

As willbe seen by reference to Figs. 1 and 5, each interchangeableformer 105 is provided with stops Z) 5 and an intermediate surfaceo,which determines the vertical outline of the cut. This surface 0 isplain or smooth,

and when the frame 7 0 is actuated to present the blank to thecutting-wheel 27 or other implement in use on the spindle 25 said blankwill be forced to engage the implement on a line indicated by thecontour of said surface '0. As above stated, a series of interchangeableformers will be supplied for controlling the formation of the design inthe blank, and to utilize the machines in the manufacture of cut glassseveral of them may be employed, one of which will form certain cuts inthe blank, a second another set of cuts, and a third another, and so on.When itis desired to change the former and blank-holder of a machine,they are withdrawn and others substituted, and this may be readilyaccomplished, for each interchangeable blank-holder is provided With alike slotted shank 83 to 'fit the head 76 and be secured by key 84., andeach interchangeable former or templet 'is equipped with a like spindle103 to en- -ter the arbor 101 and be clamped in place by screw 104. Itis distinctly to be understood that any desired implement may beattached to the spindle 25 as a substitute for the grinding- 'wheel 27shown. 'may be replaced by the usual steel disk, by

For instance, said wheel a polishing-wheel, or by a bufling device orother instrument employed in the art of manufacturing cut glass. It isalso evident that by changing the former and by substituting differentsizes of blank-holding chucks articles widely varying in shape may beorna- 'mented in the manner desired.

While manually operated indexing and blank-supporting mechanisms aredescribed, it is distinctly to be understood that said mechanisms mightbe actuated in other ways without departure from the invention, which isnot limited in these respects. So, too, certain parts of the inventionmay be used inclependently of the others and in different relations fromthose shown, if desired.

Other forms of blank-supporting and indexing mechanism may also beemployed and the parts may be differently located and differentlyproportioned with relation to each While the machine is primarilyintended for cutting or ornamenting glass, it isnot limited to anyspecific use, for it may be emversely indexing said blank-carrier.
